after years of neglect.
Police seized €810,000 ($1 million) of assets and banned her company, Cavaco, from doing any further business with public administration.
Cavaco has spent €8 million (almost $11 million) on restoration projects within Pompeii, but the site remains in danger after years of neglect.
Five others are being investigated, including the site director, Marcello Fiori and the director of restoration, Luigi D'Amora.
Cavaco's arrest occurred one day before the EU had planned to take control of the restoration. One of the EU's primary goals is to improve transparency and enforce regulations.
